BOTTLE-sToPPER.

SPECIFICATION forming part of Letters Patent No. 600,901, dated March 22, 1898.

Application filed llecemher` 28, 1897. Serial No. 663,9 84;. (No model.)

To alt whom it may concern:

Be it known that I, ALFRED VOELKER, a citi zen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Bottle-Stoppers,which improvement is fully set forth in the following speciiication and accompanying drawings.

My invention consists of a bottle-stopper formed of a cork or stopper proper, a valve thereon, a spring for closing said valve, and

j a collar on the stem of the valve for opening the latter, said head being movable, so that the tension of said spring may be adjusted.

Figure l represents a vertical sectional view of a bottle-stopper embodying my invention, showing the valve closed. Fig. 2 represents a vertical sectional view of said bottle-stopper, showing the valve open. Fig. 3 represents a top plan view of said stopper. Fig. 4 represents a bottom plan View of said stopper.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a piece of cork adapted to lform the stopper proper, the saine having therein the bushing B, which is open throughout and has its lower end constituting a seat for the valve C, whose stem D passes freely through said bushing B and is guided by the same, said stem being hollow and having in it, near its lower end, the opening E, which is uncovered when the valve C is lowered, so that the iiuid in a bottle to which the stopper is applied may enter said stem and so be discharged. When, however, the valve returns to its closed or normal condition, the opening E is closed by the bushing, and thus the passage of the fluid through the stem is prevented.

F designates a collar on the valve-stern above the cork A, and G designates the head of the cork, which head is preferably formed of metal and has the bushing B connected with it, the valve-stem freely passing through said head.

Interposed between the collar F and head Gr is the coiled or other spring I-I, whose tendency is to force said collar, and consequently the stem D, upwardly or outwardly, whereby the valve C will be held on its seat or in closed condition. The collar is interiorly screwthreaded, and the stem is eXteriorly similarly constituted, whereby said collar may be rotated on the stemup or down, so that the tension of the spring I-I may be adjusted relatively to the pressure required to retain the valve properly on its seat.

It will be seen that the ngers may be applied to the collar and a proper part of the cork or neck of a bottle, so as to move said collar toward the head of the cork, -whereby the valve C is opened and the opening E uncovered. The bottle will be overturned or decanted, and so the iiuid or liquor flows through the stem and escapes therefrom at the outer end thereof, said end or end pord tion acting as a nozzle or pour-O.

Vhen the collar is let go, the spring H quickly closes the valve and restores the opening E within the bushing, whereby the flow of iiuid or liquor ceases.

The head G strengthens the top of the stopper proper and supports the spring receiving the pressure thereof, avoiding injury to said head. Furthermore, when it is desired to close or lock the valve and render it im- .movableg especially for purposes of transportation, packing, &c., the collar will be screwed down to the full extent, thus controlling the stem and preventing opening of the valve, the effect of which is evident.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is

l. A bottle-stopper consisting of a stopper proper, a bushing therein, a valve at the base of said bushing, a hollow stem carrying said valve and freely passing through said bushing and outside of the head of the stopper, a collar and a spring interposed between said collar and head, said collar being movably IOO scribed, a stopper having a bushing therein, collar being movably fitted in said stem for a hollow Valve-stem passing freely through adjusting the position of the Valve and th said bushing, the base of the latter forming tension of the spring.

the seat of said Valve, a head on the stopper, ALFRED VOELKER. a Collar on said stern, and a spring interposed Witnesses:

between said collar and stem, said head be- JOHN A. WIEDERSHEIM,

ing connected with said bushing and said WM. C. WIEDERSHEIM.
